NVMe IP with PCIe Gen3 Soft IP reference design manual

PublishTime：2022-03-17

■ NVM Express (NVMe) defines the interface for the host controller to access solid state drive (SSD) by PCI Express. NVM Express optimizes the process to issue command and completion by using only two registers (Command issue and Command completion). Besides, NVMe supports parallel operation by supporting up to 64K commands within single queue. 64K command entries improve transfer performance for both sequential and random access.
■ In PCIe SSD market, two standards are used, i.e., AHCI and NVMe. AHCI is the older standard to provide the interface for SATA hard disk drive while NVMe is optimized for non-volatile memory SSD). The comparison between both AHCI and NVMe protocol in more details is described in “A Comparison of NVMe and AHCI” document.
